Nov 22, 2021 · The grandfather of all waveforms is the secondary ignition waveform. 2. Oct 17, 2012 · For this reason if an ignition primary originates on the primary, it will askew your secondary waveforms.
A secondary ignition waveform can be broken down into three parts. This is how secondary waveforms should look. .
Jul 30, 2021 · A primary ignition voltage waveform will be more stable compared to a secondary one. First, the area of the waveform that shows dwell where the secondary of the coil is saturated with energy from the primary.
Place the COP probe squarely onto the top of the COP unit to be tested, this will now pick up the secondary pattern.
Ignition. MacFadyen on topic Secondary ignition waveform.
The coil begins charging up full of current.
The oscillations are magnetic interference from a working ignition. I started off at a Tune-Up shop using a Sun Super-Sleuth. <strong>Secondary Ignition waveform analysis is becoming a lost diagnostic method.
The first thing to clarify is the name of the. . Along with testing COP systems, the Coil-on-plug and signal probe can also be used to obtain a secondary ignition waveform on conventional ignition systems. Place the COP probe squarely onto the top of the COP unit to be tested, this will now pick up the secondary pattern. *The parade pattern displays individual cylinders side by side from left to right, in firing-order sequence.
If you’re testing primary ignition, you should use an attenuated test lead to avoid damaging your scope. class=" fc-falcon">Secondary ignition waveforms tell a long story.
And when the mood strikes you to scope secondary ignition, keep in mind that secondary waveforms look a lot like primary waveforms.
The secondary ignition waveform As seen in Figure 1 , the voltage required to fire the plug is determined by the greatest gap in the circuit.
The secondary reacts by also going low.
